IMPROVEMENT IN MACHINERY FOR MAKING NAILS.

TO ALL WHOM IT MAY CON CERN:

Be it known that I, THADDEUS FOWLER, of Seymouigin the county of NewHaven, and State of Oonnecti cut, have invented and made a certain newand useful Improvement in Machinery for Making Horse-Shoe Nails; and Ido hereby declare the following -to be a full, clear, and exact.description of the said invention, reference being had to the annexeddrawing, `making part of this speoiiication, wherein- Figure 1 is a sideview of my machine for rolling out the body of the nail'and separatingthe nails from a bar.

Figure 2 is a sectional -plan with the upper roller removed, and'showing the mode in which the nails are separated at their points.

Figure 3 shows the bar in side and edge views `in the condition in whichit is prepared before presentation to this machine; and v Figure 4 is aside and edge view of the nail after being acted on by this machine.

Similar marks of reference denote the same parts.

Nails have heretofore been manufactured from rods by rollers acting onopposite sides to reduce the rod into the form of a nail. Diilicultieshave been experienced in this mode of manufacture, in consequence ofrollers not corresponding'in their action, for if the nail blanks', intheir first reduction, are too long or too short but a hairs ,breadth oneach nail, the nails on the rod are spoiled by the impression ofthesecond pair of rollers not coming upon the proper part of thenail-rod, especially towards the last end of the rod The rnature of mysaid invention consists in a pair of rollers that feeds the nail-rodalong by taking against the sides ofthe heads formed in the irstreduction; thereby each nail-blank is moved along the proper distance,

and thon the rollers cease their hold upon the rod, hence there is aprogressive feed of the nail-rod, and the i diiculty before mentioned isavoided, and all the reductions ot' the nail-rod subsequent to the firstare determined in position by the feeding movement acting against thenail-heads successively. .I make the horsewshoe nail in the requiredpointed form by dividing the reduced nail-blank by a diagonal cut thatleaves the nail with :the point on the line of one side, and Istraighten the nail and finish it by mechanism forming the subject of aseparate application. y

In tbe-drawing, a represents the shank portion, and b the heads in thenail-rod. These are formed by running` a rod through a pair ofrollersthat acts upon, the edges of the rodleaving the same in about the shaperepresented in iig. 3; The nail-rod thus prepared is laid into a trough,c, in which it may be steadied by hand or aspring-clamp to keep it inplace asvdrawn along progressively by the pair of rollers d e. Theserollers claw are upon the shaftsf and y that are geared together by thewheels L, and driven by competent power. Upon the edges ofthe rollers de are cam-shaped reducing surfaces, it', of a shape to reduce and extendthe blank for two 'nails the prop cr extent between thc heads, andadjacent tothese cam surfaces t' are sectional -langes o s, thesectional flange o on the roller d being towards one edge of thatroller, while the sectional ange s on the roller e is towards the otheredge, so that there is between the said flanges, when they come aroundopposite to each other, an opening of a width corresponding to the widthof the shank a of the nail-blank, as seen in iig. 5, where the rollersare shown detached. When the advancing ends of the sectional flanges o scome around, one passes on one side, and the other on the other of theshank a, and come up against the head1: of the nailblank that has beenstanding between the rollers d and e, unacted upon by said rollers afterthe caro-shaped reducing surfaces left said nail-blank upon the previousrevolution of the rollers d e. As soon as the ends ot' vo s take thehead of` the nail-blank, the nail-rod is drawn along and reduced betweenYone pair of heads'and' the next pair of heads, so asto form theshanksof the proper thickness and length. This movement passes the previouslyrolled pair of nails along' to and between the cutting apparatus. h is astanding cutter, so placed that tho same s below the point where thopairs ot' nail-heads have to be separated at the time the nail-rod isstationary, and lis a diagonal cutter, so placed as to be on thelinewhere the respective nails are to be separated to form the points, by adiagonal cut, and mis a cutter on a lever, u, to come down over thecutter L, and n is a diagonal cutter on the same lever, matching thecutter l. This lever u is actuated by the cam q, that 'is revolved inunison with the rollers d' e, and acts upon the lever u to separate thenails transversely between thc The nails are to be straightened andfinished by separate or after-acting mechanism. l

W'hat I claim, and desire to secure by Letters Patent, is

1. Moving the rod of blanks forward, and adjusting successively eachblank to its proper position, before the dies bite upon it, by means ofthe lateral flanges o s, arranged and operating in the manner hereindescribed.

2. I claim combining with devices for feeding the nail-blank thetwopairs of cutters L and m and Z and n, arranged substantially asdescribed.

3. I claim the combination of the cutters L and m, land n, with therollers d and e, formed with camshaped surfaces z' and flanges o and s,as and for the purposes specified.
